This paper presents the study of bidirectional ac/dc converter PWM with feedforward neural network control. Bidirectional ac/dc converter act as a utility interface between ac grid and distributed energy resources or renewable energy resources. The converter facilitates a battery energy system for power charge or discharge to compensate for the dc bus voltage deviation during severe distribution conditions. Due to these disturbances such as fault occurrences, system loads and varying environmental condition causes overshoot and undershoot problem. This proposed system reduces the overshoot and undershoot to very low value. Current harmonics in a PWM bidirectional ac/dc power converter are reduced considerably by using feedforward neural network. This paper present a modified feedforward technique having neural network and existing model with feedforward technique having PI controller will be compared. Both schemes are explain with experimental result. The proposed simplified PWM provides the better voltage regulation and high fundamental dc output voltage with lower THD and high efficiency. This proposed project has larger fundamental output voltage in inverter mode. Both simulation and experimental results verify the validity of the proposed PWM strategy and control scheme.

Trimming is one of the finishing operations in manufacturing process. To remove the extra material of the edge surface of the component is called trimming operation. Deep drawing is one of the manufacturing process used to manufacture parts like pen cap, bowls etc. After deep drawing process extra material is remained on the edge of the component. Removing of this material by conventional trimming machine is very tedious process. Which leads to labour fatigue and time required to trim the one component is more due to this productivity is decreases. To overcome this problem automation is implemented in this conventional machine by using PLC, stepper motors, sensors, and various drives. Due to this automation production rate is increased and cycle time/ product is reduced. Number of component can be trimmed on this automated trimming machine. This report is giving the information of construction of automated trimming machine, list of elements required to this project, design idea of machine, costing of the machine and end result by implementing this automation on productivity.

Demand for modifications is increasing throughout the world parallel to develop the existing highway materials to fulfil the increasing demand of vehicles. Some materials produce good effect and enhance the strength as well as qualities of bitumen. On the other hand, some materials are responsible for adverse effect on the bitumen. The present study, the focus was given to find the effect of Beach Sand in bituminous concrete mixes. Samples were prepared by varying the amount of Beach Sand 5%, 10%, 15% and 20% by weight of aggregate mix. Marshall Property test, Moisture susceptibility test (ITS and RTS) were conducted as per MoRT&H, AASHTO and ASTM standards. The stability value of bituminous mixes were found to be decreasing with increase in Beach Sand content in bituminous mix at the OBC of the conventional mix. Here it is essential to note that instead of conducting the tests at OBC of respective non-conventional mixes OBC is kept constant (i.e. OBC of conventional mix). Since the objective of this project is to make the mix economical, a slightly different approach of maintaining a constant bitumen content is adapted. It is understood that Bitumen is the costliest material used in flexible pavement and every possible effort is to be made to reduce the quantity of bitumen to be used.

Numerous anonymization methods, such as simplification and bucketing, are designed for privacy preserving micro data publishing. Many works shown that generalization lose considerable amount of information, especially for high dimensional data object. But Bucketization does not prevent membership disclosures and do not apply for data that do not have a clear separation among quasi-identifier characteristics and delicate attributes. In this work, we present a novel technique called slicing partitioning on the data both horizontally and vertically. We show that slicing preserves data utility better than oversimplification and can be castoff for involvement disclosure protections. Another important use of slicing is that it can be used in high-dimensional data. We show how slicing can be used in attribute disclosure protection and developed an effectual procedure for adding the sliced data that obey diversity requirements. Our experiment confirms that slicing preserves better utility than generalizations and more effective than bucketizations in workloads involving the sensitive attributes. Our work also demonstrates that slicing can be used to prevent membership disclosure

In automobile sector we always try to make everything perfect around us and there are major problem is that puncture in tyre while running. We have developed tubeless tyres but that’s not a perfect solution, so there is a major need of improvement in this sector. In this paper self-inflating tyre system that ensures that tyres are properly filled at all times. Our design successfully implements the use of a portable compressor that will supply air to all tyres via hoses and a rotary joint fixed between the wheel spindle and wheel hub at each wheel. The rotary joints effectively pass air to be channeled to the tyres without the tangling of hoses. If pressure is below the desired, the compressor will refill in the tyre. If it is above desired, excess pressure will release through a valve. With the recent oil price growing concern of environmental issues, this system addresses a potential improvement in tyre wear reduction and an increase in handling & tyre performance in diverse conditions.

Glaucoma is a chronic eye disease which leads to vision loss. It is a silent theft of sight. Early detection of glaucoma can potentially reduce the risk of blindness. However many patients are unaware of the disease, because it progresses slowly without easily noticeable symptoms. In recent studies, there is no effective method for low-cost population-based glaucoma detection or screening. In this work, the propose method is cup to disc ratio (CDR) assessment, using 2-D retinal fundus images. First, the image is pre-processed by converting the image into HSI and applying the filter. Followed by, the optic disc is first located and segment out the optic disc position and identify the optic disc and optic cup and reconstructed using a novel sparse dissimilarity-constrained coding (SDC) approach Subsequently, the reconstruction coefficients from the SDC are used to compute the (CDR) Cup to Disc Ratio for the testing disc.
